A simple relative laser power meter was designed and built according to the principles of the ‘‘pedestal’’ calorimeter. The principles and specific details of the construction are given. The time response was measured and characterized by the time constants of the heating (‘‘laser on’’) and cooling (‘‘laser off’’) of the receiving element. The time constants were 1.46 s for heating and 1.34 s for cooling.
